Any particular 6fd7 brand you suggest? I will keep Bottlehead crack just for HD650. And use WA6 for LCD2. Is sophia a good choice? I still can cancel it if it's not

I ordered Sophia Princess Mesh Plate 274B today, What power tubes you think work best with LCD-2 and HD-650? Is 1 matched pair of 6GL7/6EM7 plus one pair of 6GL7->6DE7 Teflon tube adapters from Woo site a good set of tubes?

Hello Forum! Purchased used WA6-SE in new condition with stock tubes (NOS International Servicemaster 5AR4 and US RCA 6DE7) I love the amp and sound with LCD-2 right out the box!! However, HD-650 sound horrible. Very muddied and with no detail. Headphones by themselves sound great! I own...
